Inside a 4D Film
A lot of people think that 3D films are pretty cool. When you watch a 3D film, it sometimes feels like you can reach out and touch the things that you see. In the future, however, 3D might be replaced by something even more advanced: 4D. What you see in a 4D film is the same as what you see in a 3D film. The screen is the same, and the glasses are the same. 4D films are different because they don’t use 3D technology. People in the audience also feel physical things during the films. Let’s look at a few examples. Let’s say that you are watching a film about earthquakes. If you are watching a 4D film, maybe your seat will suddenly start to shake. It will feel like you are in the middle of an earthquake, but you are not. The 4D effects make your seat shake. Or perhaps during the film, one of the characters gives flowers to another character. The people in the cinema might suddenly smell flowers. The point of 4D films is to make people feel like they are in the film. When we watch films these days, we only use two senses: our sense of sight and our sense of hearing. If we use our other senses, the film might feel more real to us. 4D films already exist. The film Avatar was released everywhere in 3D, but in Korea and Hong Kong, it was also released in 4D. People who watched Avatar in 4D feel wind and rain. They also smelled smoke from the weapons in the film, and sometimes their seats moved. Will 4D replace 3D films? It is possible, but we can’t be sure yet. One problem with 4D films is that it is very expensive to show them in theaters. Before a theater shows a 4D film, it has to buy a lot of special equipment. However, 4 films are catching on. Other films shown in 4D include Shrek 4-D, and Iron Man 3.
5. What would only happen during a 4D film?

The ability to conduct electricity is one of the key properties of a metal. Other solid material such as silicon can conduct electricity but only effectively at certain temperatures. Also, some substances such as salt (sodium chloride) can conduct when molten or when dissolved in water. The ability of metals to conduct electricity is due to how their atoms bond together. In order to bond together the metal atoms lose at least one of their outermost electrons. This leaves the metal atoms with a positive charge and they are now strictly ions. The lost electrons are free to move in what are known as a sea of electrons. Since the electrons are negatively charged they attract the ions and this is what keeps the structure together.

An electric current is a flow of charge and since the electrons in the sea of electrons are free to move they can be made to flow in one direction when a source of electrical energy such as a battery is connected to the metal. Hence we have an electric current flowing through the wire, and this is what makes metals such good conductors of electricity. The only other common solid conducting material that pencil users are likely to encounter is graphite (what the 'lead' of a pencil is made from). Graphite is a form of carbon and again the carbon atoms bond in such a way that there is a sea of electrons that can be made to flow as an electric current. Likewise, if we have an ionic substance like salt we can make the electrically charged ions flow to create a current but only when those ions are free to move, either when the substance is a liquid or dissolved in water. In its solid state an ionic substance like salt cannot conduct electricity as its charged ions cannot flow.

Electrical insulators are substances that cannot conduct electricity well either, because they contain no charged particles or any charged particles they might contain do not flow easily. Water itself is a poor conductor or electricity as it does not contain a significant amount of fully charged particles (the ends of a water molecule are partly charged but overall the molecule is neutral). However, most water we encounter does contain dissolved charged particles, so it will be more conductive than pure water. Many of the problems that occur when touching electrical devices with wet hands result from the ever-present salt that is left on our skin through perspiration and it dissolves in the water to make it more conductive.

Salt in its solid state is not able to conduct electricity because________.

It’s in Your Genes
Every human being has about 25,000 genes. Your genes are part of your DNA. They give your body instructions on how to develop. For example, if your genes tell your body to build long, thin fingers, then you will have long, thin fingers. Your genes come from your parents, and they decide everything about you. They decide your hair colour, your eye colour, your height, and so on. Genes are still a bit of a mystery to scientists, but they are learning new things about them all the time. One issue that people often debate is this: Do our genes influence our personalities? These days, most people agree that the answer to this question is yes. Recent studies have shown that genes especially influence our self-control and our sense of purpose. Your sense of purpose is your desire to have goals in your life. If a person really wants to accomplish something and do well in life, he or she has a sense of purpose. A person who does not care about goals has no sense of purpose. Although scientists agree that our genes influence our personalities, there is another question. How much do they influence us? Can we control ourselves, or do our genes control us? People everywhere are still debating this issue. So far, we don’t really have an answer. Genes also affect your health. If a gene has a problem, it is called a mutated gene. Some mutated genes can cause diseases. That is why if a person has a certain health problem, his or her child is more likely to have that same problem. The child also has the mutated gene. As scientists and doctors learn more about genes, they are also developing a new kind of medicine: gene therapy. Therapy is help for a mental or a physical problem. Gene therapy means fixing or replacing mutated genes. Scientists are still experimenting on gene therapy. It is possible that in the future, gene therapy will help doctors prevent and cure diseases that are caused by mutated genes.

Read the following passage and choose the best answer (A, B, C, D):
Although he created the game of basketball at the YMCA in Springfield, Massachusetts, Dr. James A. Naismith was a Canadian. Working as a physical education instructor at the International YMCA, now Springfield College, Dr. Naismith noticed a lack of interest in exercise among students during the wintertime. The New England winters were fierce, and the students balked at participating in outdoor activities. Naismith determined that a fast-moving game that could be played indoors would fill a void after the baseball and football seasons had ended. First he attempted to adapt outdoor games such as soccer and rugby to indoor play, but he soon found them unsuitable for confined areas. Finally, he determined that he would have to invent a game. In December of 1891, Dr. Naismith hung two old peach baskets as either end of the gymnasium at the school, and, using a soccer ball and nine players on each side, organized the first basketball game. The early rules allowed three points for each basket and made running with the ball a violation. Every time a goal was made, someone had to climb a ladder to retrieve the ball. Nevertheless, the game became popular. In less than a year, basketball was being played in both the United States and Canada. Five years later, a championship tournament was staged in New York City, which was won by the Brooklyn Central YMCA. The teams had already been reduced to seven players, and five became standard in the 1897 season. When basketball was introduced as a demonstration sport in the 1904 Olympic Games in St. Louis, it quickly spread throughout the world. In 1906, a metal hoop was used for the first time to replace the basket, but the name basketball has remained.

Getting Focused and Flexible with Yoga
In a small room, men and women are getting a great workout. However, there are no weights in this gym. The only piece of equipment is a small rubber mat. On it, they strike unusual poses which are held for minutes at a time. An instructor goes from student to student urging them to relax and breathe deeply, while inspecting their posture. In the end, through the art of yoga they hope to balance their body, mind, and spirit. Yoga originated in India over 2,000 over years ago. The first yogis weren’t looking to lose weight or get themselves in great shape. Instead, they practise yoga to help them achieve liberation. Yoga became an important part of Hindu culture, and it is mentioned in nearly all of the religion’s ancient scriptures. It wasn’t until the 19th century, however, that Westerners took notice of yoga. In the 1890s, Swami Vievekananda became the first yoga teacher to take on Western students when he toured the US and Europe. His lessons focused primarily on the spiritual aspects, and his speeches intrigued many intellectuals, but it would take some time before yoga would catch on with the masses. That didn’t happen until the 1980s when many Americans and Europeans embraced yoga during a worldwide exercise boom. Yet once it took hold, yoga has increased popularity year by year. It is estimated that over 20 million Americans now practice yoga regularly. A main reason why contemporary people are hooked on yoga is that it helps to relieve work-related stress. Students are taught to breathe slowly and deeply while concentrating on the present moment and letting go of the past. The challenging postures help to balance the negative effects people experience from sitting in chairs all day. The poses also help people to regain flexibility and improve circulation, which is particularly useful to the elderly. As yoga became commercialized in the West, many new branches were formed. Ashtanga yoga moves at a fairly quick pace, flowing from pose to pose, power yoga, on the other hand, offers workouts that are designed to increase strength. Another popular style, hot yoga, has students practise in hot environments to help them burn more calories. If you are thinking of studying yoga, try them all and let your heart decide which one is best for you.

The Invention of the Periodic Table
If you are looking to gain a better understanding of the world around you, chemistry is the perfect subject to study. It is an examination of matter, its properties, and its interactions with everything around it. Where physics often deals with concepts and theories that are difficult to test and observe, chemistry principles can easily be applied to medicine, cooking, and several other areas. At the heart of all these discoveries is one vital chart that organizes elements based on their atomic number and chemical properties: the periodic table. Although the first periodic table was published in 1869, it was a work in progress for hundreds, if not thousands of years. Since ancient times, people have been fascinated with elements such as gold, tin, and copper in their natural forms. They were mined and used to make jewellery, weapons, coins, and many other things. Over time, people became more curious about these metals and how they were composed. In ancient Greece, Aristotle and other philosophers claimed things were made from the elements of earth, water, fire, and air. For years, this theory was accepted. Then people began to reevaluate this concept during the Age of Enlightenment. In 1661, Irish scientist Robert Boyle defined an element as something that “cannot be broken down into a simpler substance by a chemical reaction”. Over a century later, French chemist Antoine-Laurent Lavoisier would publish the first modern textbook on chemistry. In it, he listed several substances which he believed should be classified as elements into two categories: metals, and non-metals. Although his work wasn’t completely accurate, it represented a major step forward at the time. Over the next century, scientists started to classify the elements into different groups depending on their properties and atomic weights. However, it is Russian chemist Dmitri Mendeleev who is usually credited as the first person to make a periodic table. Although other scientists had submitted tables, they were eventually rejected by the scientific community for a lack of detail. Mendeleev arranged all of the elements according to their atomic mass. He was even smart enough to leave empty spaces for elements which hadn’t been discovered at the time. Although Mendeleev’s periodic table wasn’t perfect, it set the format which is similar to the one used today.

Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions:
    Who talks more - men or women? Most people believe that women talk more. However, linguist Deborah Tannen, who has the studied the communication style of men and women, says that this is a stereotype. According to Tannen, women are more verbal - talk more - in private situations, where they use conversation as the “glue’ to hold relationships together. But, she says, men talk more in public situations, where they use conversation to exchange information and gain status. Tannen points out that we can see these difference even in children. Little girls often play with one ‘best friend’ and their play includes a lot of conversation. Little boys often play games in groups, their play usually involves more doing than talking. In school, girls are often better at verbal skills, while boys are often better at mathematics.
    A recent study at Emory University helps to shed light on the roots of this difference. Researchers studied conversation between children aged 3-6 and their parents. They found evidence that parents talk very differently to their sons than they do to their daughters. The startling conclusion was that parents use more language with their girls. Specifically, when parents talk with their daughters, they use more descriptive language and more details. There is also far more talk about emotions, especially with daughters than with sons.

Which of the following phrases best explains the meaning of the word “verbal”?

The American type of football was developed in the 19th century from soccer and rugby football. Played by professionals, amateurs, college and high school students, or young children, football in American is one of the most popular sports besides basketball and baseball. It attracts millions of fans each fall and people are very supportive of their favourite teams. The football playing field of today is rectangular in shape and measures 100 yards long and 53.5 yards wide. White lines are painted on the playing field to mark off the distances to the end zone. The games is divided into four quarters, each fifteen minutes long. The first two quarters are known as the first half. There is a rest period between two halves which usually last about fifteen minutes. Each team has eleven players. Each team has offensive players who play when the team has possession of the ball and defensive players who play when the other team has the possession of the ball. Because of the body contact players have during the game, helmets are worn to protect their head and face area, whereas pads are worn to protect the shoulders, arms, and legs. Also, there are officials carrying whistles and flags to make certain that the rules of the game are followed during the game. The football is made of leather and is brown in colour. It is shaped much like an oval and has white rings near each end of the football. These rings help the players see the ball when it is thrown or someone is running with it. The eight stitches on the top of the football help the players to grip the ball when throwing or passing. The most famous game of the year is Super Bowl that is played in January or February. It is televised around the world and is watched by millions of people each year.

Why are there white rings on each end of the football?
